In the above conventional technique, the second rotating body is located closer to the aligned seedlings than the first rotating body, and thus the paper cylinder of the seedling raising container is not sufficiently filled with the soil. When the paper cylinder is crushed and the second rotating body is separated, it may come into contact with the seedling row next to the seedling row and separate up to the next seedling row or break the paper tube of the next seedling row. there were.

Further, since the first rotary body and the second rotary body are moved back and forth by a predetermined distance at the moving end of the lateral movement mechanism, a mechanism for moving the first rotary body and the second rotary body back and forth is required. Therefore, the transmission of rotational power to the first rotating body and the second rotating body is complicated.

The present invention solves the above problems,
By separating the seedlings into individual seedlings with a simple mechanism,
The purpose of the present invention is to provide a high-performance, high-efficiency separating seedling separating device that continuously separates individual seedlings, and to dramatically expand transplant cultivation.

A pair of shafts 33 and 34 are provided from inside the separating part frame 30 to the outside of the separating part frame 30. The pair of shafts 33 and 34 are parallel to the moving direction Mc of the lateral moving mechanism 10 and of the vertical moving mechanism 20. The positions in the moving direction are the same, gears with the same number of teeth are meshed with the pair of shafts 33, 34, and they rotate in opposite directions at the same rotational speed.

A pair of shafts 33, 34 outside the separating portion frame 30 are provided with a pair of elastic rollers 31, 32 as separating rotating bodies fitted therein. Since the rollers 31 and 32 are fitted on the pair of shafts 33 and 34 having the same position in the moving direction of the vertical moving mechanism 20, the rollers 31 and 32 are provided at the same distance from the aligned seedlings P. The rollers 31 and 32 are cylindrical sponge bodies,
The rollers 31 and 32 are positioned so as to be in contact with the upper and lower portions of the side surface of the aligned seedling P placed on the belt 25, and the pair of rollers 31 and 32 are arranged at intervals narrower than the paper tube diameter of each individual seedling Pa.

Further, when the pair of shafts 33, 34 rotate at the same speed in the opposite directions, the pair of rollers 31, 32 rotate at the same speed in the direction in which the surfaces facing each other move away from the aligned seedling P, and The peripheral speed is about three times as fast as the moving speed of the lateral moving mechanism 10.

In FIG. 4, the side for moving the aligned seedlings P in the lateral direction by the lateral moving mechanism 10 is the first roller 31 as the first rotating body, and the side for moving away is the second roller 31. The second roller 32 as a body is used.

The first roller 31 is a seedling from which the aligned seedlings P are separated.
The position contacting the moving side surface of Pa by elastically deforming, the surface of the first roller 31 in contact with the aligned seedling P is normally rotated in the moving direction Mc of the separated seedling Pa, and the aligned seedling of the first roller 31. The speed of the surface in contact with P is faster than the moving speed of the aligned seedlings P.

The second roller 32 is located at the same distance as the first roller 31 from the aligned seedling P. Since the second roller 32 is not in contact with the aligned seedling P, it is not deformed and is separated. Seedling
It is located in front of the moving direction Mc of Pa and is rotating in the opposite direction to the first roller 31, and when the separated seedling Pa that was not separated by the first roller 31 moves as it is, the moving front surface becomes the second. Contact the roller 32 of.

A pair of flat belts 38 are provided outward from the opposite sides of the rollers 31 and 32 to the aligned seedlings P by a shaft provided below the separating frame 30. The flat belt 38 receives the individual seedlings Pb separated and fed from the rollers 31, 32, sandwiches and conveys the seedlings Pb in the middle part of the paper tube, and feeds them to the opposite side of the aligned seedlings P.

A pair of flat belts 39 is formed by a shaft provided below the separating frame 30 in a direction perpendicular to the end of conveyance of the flat belts 38.
To provide. The flat belt 39 receives the individual seedlings Pb delivered from the end of the transport of the flat belt 38, and sandwiches the upper part of the paper tube to convey and deliver it.

Next, the operation will be described.

The lateral movement mechanism frame 12 of the lateral movement mechanism 10 has its predetermined moving end, and the aligned seedlings P are vertically moved on the lateral movement mechanism 10.
The row of seedlings Pa separated from the front end of the aligned seedlings P is in contact with the seedling regulation belt 5 as a first roller.
31 is elastically deformed and sent to the contact position.

When the shaft 16 or the like is rotated by an appropriate means and the lateral movement mechanism frame 12 is laterally moved, the aligned seedlings P are laterally moved and the rollers 31, 32, the flat belts 38, 39, etc. are rotated.

By the lateral movement of the lateral movement mechanism frame 12, the row of separated seedlings Pa in the front row of the aligned seedlings P moves in the illustrated movement direction Mc as shown in FIG. Deform 31 and touch its front end.

At this time, the surface of the first roller 31 in contact with the side surface of the separated seedling Pa of the aligned seedlings P is normally rotated in the moving direction Mc of the separated seedling Pa and is rotated rightward in the drawing, The separated seedling Pa is sandwiched between the next row of subsequent seedlings and the first roller 31 and rotated, so that the rotational force is reliably transmitted, and the separated seedling Pa is rotated to the left. Therefore, the separated seedling Pa is peeled off from the connection portion of the next seedling of the separated seedling Pa, and subsequently separated from the connection portion with the subsequent next seedling row to be separated into individual seedlings Pb without difficulty. .

Since the speed of the surface of the first roller 31 in contact with the separated seedlings Pa is faster than the moving speed of the aligned seedlings P, the separated seedlings Pa and the next succeeding seedling row It is sandwiched between the roller 31 and the roller 31 and rotated, and is moved at a speed higher than the moving speed of the aligned seedlings P while rolling, so that the seedling Pa to be separated is separated from the seedling next to the seedling Pa and is reliably separated. .

The separated seedling Pb also contacts a second roller 32 provided in front of the moving separated seedling Pa, and the second roller 32 rotates in the opposite direction to the first roller 31. Therefore, it is sandwiched between the pair of rollers 31 and 32 and is fed to the opposite side of the aligned seedlings P while standing.

At this time, the first roller 31 is elastically deformed and brought into contact with the moving side surface of the seedling to be separated.
Even if the roller 32 of is located at the same position as the first roller 31 from the aligned seedling P, the second roller 32 is located in front of the moving direction Mc of the separated seedling Pa and follows the separated seedling Pa. Be far from the seedlings of.

In addition, the seedling Pa to be separated is the first roller.
Even if the seedling Pa is not separated by 31, the separated second seed roller Pa moves as it is.
The moving front surface of the first roller 31 is in contact with the first roller 31, and the first roller 31 is rotated in the direction opposite to the first roller 31 to be separated and fed out. Therefore, it is possible to prevent a separation error from occurring, and the separation is surely performed.

Then, the seedling Pb sandwiched between the pair of rollers 31 and 32 and fed out is immediately flat belts 38 and 39.
It is stretched farther and is transplanted to the main field by an appropriate transplanting device.

Further, the first roller 31 as a separating rotary member
Since the second roller 32 and the second roller 32 can be continuously contacted with and separated from the aligned seedling P, the side surface of the row of the seedling Pa from which the aligned seedling P is separated is sequentially contacted with the first roller 31 to the second roller 32. By hitting, it is continuously separated into individual seedlings Pb and fed out.

When all the separated seedling rows in the front row of the aligned seedlings P are finished and the lateral movement mechanism frame 12 reaches the moving end, the aligned seedlings P are moved vertically by the belt 25 by one row. Then, the lateral movement mechanism frame 12 subsequently laterally moves the aligned seedlings P in the opposite direction to start separation of the next row.

At this time, the second roller 32 is located at the same position as the first roller 31 from the aligned seedling P, and even if the moving direction of the aligned seedling P is changed, the first roller 31 and the second roller 31 are moved. 32
Since there is no need to change the position of the first roller 31 and the second roller
There is no need for a mechanism for moving the roller 32 back and forth, and the transmission of rotational power becomes simple. Then, as shown in FIG.
Serves as a first rotating body, and the roller 31 serves as a second rotating body, and their roles are alternately changed and separated.

Further, the belt 25 also intermittently moves the aligned seedlings P at the moving end on the opposite side of the lateral moving mechanism frame 12, and the seedlings Pa are continuously separated.

In the above embodiment, a paper tube seedling in a paper tube seedling container is shown as the aligned seedlings P, but the soil itself is hardened in a predetermined shape, or the inorganic fiber or the high density seedling medium itself is orderly connected. Even those based on molecular compounds may be used as long as they are orderly and separably connected to individual seedlings Pa.

Further, although the rollers 31 and 32 of the cylindrical sponge body are shown as the first rotating body and the second rotating body, either or both of the first rotating body and the second rotating body are shown. May be belt-shaped.

Although the pair of rollers 31 and 32 rotate in opposite directions at the same speed as the first rotating body and the second rotating body, the first rotating body and the second rotating body are shown. There may be a speed difference in rotation.

[0046]

According to the present invention, the first rotating body elastically deforms and contacts the moving side surface of the separated seedling, and the second rotating body has the same distance from the aligned seedling as the first rotating body. Since the second rotating body is located at a sufficient distance from the next seedling row following the seedling to be separated, the paper cylinder of the seedling raising container is not sufficiently packed and the paper cylinder is pushed. Even when crushed, the second rotating body does not come into contact with the seedling row next to the seedling row to be separated, the next seedling row is separated, or the paper cylinder of the next seedling row is broken.

Further, the second rotating body is located at the same position as the first rotating body from the aligned seedlings, and the positions of the first rotating body and the second rotating body are changed even if the moving direction of the aligned seedlings is changed. Since it is not necessary to change, the mechanism for advancing and retracting the first rotary body and the second rotary body is not required, and the transmission of the rotational power thereof is also simple.
